Plot barplots showing "Attempt outcome" for all burners. In other words - show how many times each of the burners has succeded/not succeeded/there was no ignition.

Focus only on observations where 'Attempt outcome' is equal to ' succeed' or 'failed'. Try to find parameters that affect the outcome. Use scatter plots, box plots or whatever you want. Once you think you found parameters that affect the attempt outcume, perform the p-values of Mann-Whitney rank test for burner number 1.

For the first two iterations of scatter plots I was trying to find patterns and look at the units of the data. I also tried to use LOF to see if there was some sort of trend going on.

In burner 1, the plot for mean steam pressure vs mean steam pressure for an hour before start seems to indicate there's a particular difference in behavior between successful and failed attempts, for the rest of the plots it's difficult to identify a pattern.

Box plot analysis for all burners to try and spot a general trend. Parameters such as mean temperature, mean steam temperature and fuel oil temperature do show a specific behavior. Doing box plot analysis for burner 1:

When ignition fails, it appears that the mean steam pressure for an hour before start is too high.

MWU test shows that h0 can be rejected for mean steam pressure, meaning steam pressure values for successful and failed attempts are in fact different.

The difference in distribution is clearly seen also in the boxplots, therefore no surprise that mean steam pressure for an hour before start also has a value of p<0.05.

Since temperature is a function of pressure, the mean temperature for the mixture of oil and steam will also reject h0.

The mean fuel oil pressure in ring 1 and the temperature of the fuel oil can't reject h0, which means these parameters are not the reason why burners are not igniting.

In conclusion, regulating mean steam pressure in such a way that the median approaches 0.74 is vital to increase the probability that the burners will ignite.
